Daisy had always longed to help endangered species of wildlife. One day she made a dream that she {#blank#}1{#/blank#}(take) to a distant land in Tibet by a flying carpet .There, the antelope told her they were killed for the wool beneath their {#blank#}2{#/blank#}(stomach). Then the carpet flew her to Zimbabwe {#blank#}3{#/blank#} she met an elephant. The elephant said they used to be {#blank#}4{#/blank#} endangered species because local farmers hunted them without mercy. {#blank#}5{#/blank#}(fortunate), their number was now increasing {#blank#}6{#/blank#} the help of the government. So when learning that more attention was paid to {#blank#}7{#/blank#}(protect) wildlife, Daisy felt happy. Her final stop was a thick rainforest. A monkey was seen rubbing a millipede insect over {#blank#}8{#/blank#}(it) body. Out of {#blank#}9{#/blank#}(curious), Daisy asked the monkey what the millipede contained. Knowing it contained a powerful drug, Daisy could hardly wait {#blank#}10{#/blank#}(share) the good news with WWF.

    Scientists found that air pollution may be responsible {#blank#}1{#/blank#} a significant reduction in intelligence. The research conducted by the World Health Organization (WHO) in China {#blank#}2{#/blank#} (show) that air pollution led to big falls in test {#blank#}3{#/blank#} (score) for languages and arithmetic. The study is called "The impact of exposure to air pollution on cognitive (认知的)performance ". It was published in the Proceedings of the National Academy of Sciences journal. The study took place over four years. Researchers analyzed speaking and arithmetic tests taken by 20 000 people of all ages. They said, "Polluted air may prevent cognitive ability {#blank#}4{#/blank#} people become older.”

    The study is a warning to the rest of the world, {#blank#}5{#/blank#} (especial) to those in cities. Over 91 percent of the world population live in areas with {#blank#}6{#/blank#} (poison) air and air pollution is the {#blank#}7{#/blank#} (four) highest cause of global deaths. Researchers discovered that {#blank#}8{#/blank#} longer people were exposed to polluted air, the greater their intelligence went down. They said air pollution caused a year's worth of lost education. For those {#blank#}9{#/blank#} were over 60 years old, this could be several years. A researcher warned, "There is no shortcut {#blank#}10{#/blank#} (solve) this issue. Governments really need to take effective measures to reduce air pollution."

Invented {#blank#}1{#/blank#} early twentieth-century America by Richard Drew, Scotch tape can be used to fix almost anything. However, there is more to this fix-it-all than just that. Sticky yet easily removed, Scotch tape was designed for use in painting cars—to mask off areas that should not {#blank#}2{#/blank#} (paint). The tape soon found other uses. During the 1930s, people didn't have much money, so they couldn't throw away damaged things; they had to repair them. Drew's painting tape became a popular, money-saving fix for everything from torn clothing to broken eggs. Since then, people {#blank#}3{#/blank#} (find) all sorts of creative ways to use the sticky tape.

Cai Zhengjun lost his hearing when he was just in eighteen months old, as a result of a high fever. {#blank#}1{#/blank#} (fortunate), his parents loved him and supported him as much as possible. They were determined to see their son equipped with the necessary life {#blank#}2{#/blank#}(skill) needed to lead a normal life. Cai, however, didn't understand the support they provided. it was after many years that he realized what they were trying to do. Today. Cai's role has changed from a silent observer in life {#blank#}3{#/blank#}a source of empowerment for his fellow hearing impaired peers.
